SANITARY CUSPIDOR.

Specification of Letters Patent.

Patented J an. 19, 1915.

To all whom it may concern Be it known that I, CHARLES S. HARPER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Sanitary Cuspidors, of which the following is a specification.

This invention relates to improvements in cuspidors which are particularly adapted for use in passenger cars where the contents may be carried off through a Waste pipe passing through the floor of the car, and to rooms in buildings where the waste pipe can be connected with the sewer, thereby making the device stationary in character in order to render it entirely sanitary, but

it is equally adapted for embodiment in a portable article, the same as cuspidors now in common use.

The object of the invention is to provide an automatic closure which may be readily opened by pressure from the foot of a person desiring to use it, and which will close automatically upon the removal of the pressure, and when thus closed will prevent the escape of ofl'ensive odors and vapors into the room or car, and when used in cars with drainage through the floor of the car will prevent counter drafts into the car through the cuspidor produced by the motion of the train, and will prevent the entrance of dust and cinders into the car through said means.

Another object of the invention is to provide a simple and durable construction which will also present a neat appearance and be readily accessible and easy of operation.

I accomplish the above objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a view in elevation of my complete invention, in its closed condition, and showing the supporting floor in vertical section. Fig. 2 is a vertical section through the device on the line 2--2 of Fig. 3, except that the cuspidor is shown in its open condition, instead of closed as in Fig. 3, and Fig. 3 is a vertical section on a plane through the dotted line 3 3 of Figs. 1 and 2 which is at right angles to the plane of section on which Fig. 2 istaken.

Like characters of reference indicate like parts throughout the several views of the drawing.

Resting upon the floor 4 is a circular baseplate 5 which supports a concentric superimposed cylindrical sleeve 6. The upper edges of the sleeve 6 are turned outwardly to provide a seat for a hemispherical bowl 7, which is removably secured to this upper turned edge of the sleeve 6 by means of screws 8 which pass through the turned edges and bowl into bars or blocks 9 located for that purpose within the bowl.

Located within the bowl 7 is the cuspidor body 10, in the shape of a funnel, the upper edges of which are even with the rim of the bowl. The bottom of the funnel merges into a vertical pipe 11 which extends down through a suitable opening in the bottom of the bowl 7 and thence through the sleeve 6 and base 5 and floor 4, making a loose sliding fit with all of said parts. The contents of the cuspidor are immediately and constantly drained off through said pipe 11 which, if the cuspidor be located in a car will discharge upon the ground, and if it be located in a building will discharge into the sewer, unless the cuspidor is to be a portable one, in which case the cuspidor body 10 will be closed at its bottom instead of discharging into the pipe 11.

Located within the sleeve 6 and secured in a fixed manner to the pipe 11 is a ring or flange 12, and seated within the sleeve on the base 5, and between the base 5 and ring 12, surrounding the pipe 11, and within the sleeve 6 is a spirally wound spring 13, tending to constantly raise the ring 12 and consequently the pipe 11 and cuspidor body 10. The walls of the sleeve 6 are provided with vertical slots 14 through which arms 15, integral with the ring 12 are extended, and these arms support an annular foot bar 16. By a downward pressure as with the toe of the operators foot, the bar 16 will be lowered by compressing spring 13 thereby lowering pipe 11 and cuspidor body 10.

Secured in a fixed manner to the pipe 11, above the ring 12 is a second ring 17. This ring 17 is arrested in its upward movement the overhanging edge of the bowl 71 at the bottom opening formed in the latter and by this means the maximum upward movement of the pipe 11 by the action of spring 13 is determined. The upper rim of the bowl 7 is preferably stiffened and finished with a wire around which the edge of the bowl is bent in the usual manner, and at two diametrically opposite portions of this rim hinge supports 18 are provided, and to these supports 18 the points of a pair of quadri-spherical covers 19 and 20 are hinged. Hinge-eyes are formed at the points of both quadri-spherical sections, and the adjacent eyes of each section or cover are hinged to the same pin, supported by its support 18. The two quadri-spherical sections of the cover are adapted to be swung upwardly into contact with each other as shown in Fig. 1 and in dotted lines in Fig. 2, and to be swung down, between the cuspidor body 10 and bowl 7 until they contact with pipe 11, in the position shown in full lines in Fig. 2, thereby opening the cuspidor. The edges of the sections which contact with each other when the sections are raised will preferably be wired at these edges to give additional strength and bearing surfaces.

The opening and closing of the cover sections 19 and 20 are secured by connecting them with the top ring 17 on the vertically movable pipe 11. This is accomplished by means of the bars 21 and 22, the lower ends of which are fastened to the ring 17, and the bars are thence continued vertically into the bowl 7 and thence outwardly in an oblique direction to positions close to the wall of the bowl 7 and below the respective hinges of the cover section, where the bars are forked in the manner shown in dotted lines in Fig. 2 and terminate with enlarged ends which are each horizontally slotted to receive pins 19 and 20 seated in sections 19 and 20, respectively, and projecting inwardly of said sections into engagement with the respective bars 21 and 22 by passing through the horizontal slots in the forked ends of said. bars. The pins 19 and 20 are at a suitable distance from the hinges of said sections to cause a swinging movement to be imparted to the sections when a vertical pressure is imparted to the pins by a corresponding movement of the bars 21 and 22. By the action of the spring 13 the pipe 11 and consequently the ring 17 to which bars 21 and 22 are fastened will be held normally at the highest position of said pipe with the consequent result that the cover sections 19 and 20, by virtue of the above described connections, will be normally held in their upper or closed positions, thereby normally closing the cuspidor. But a lowering of the pipe by a pressure, as by the operators foot upon the foot bar16, will compress spring 13 and reverse the normal operation of the above mechanism and thereby open the cuspidor. As soon however as the mechanism is released by the removal of the operators foot the action of spring 13 will automatically and immediately close the cuspidor. It will be noted that the pins 19 and 20 move in the arcs of circles around the hinges of the sections 19 and 20, instead of in vertical lines, when the sections are moved, which makes necessary the horizontal slots in the ends of the forks of the bars 21 and 22.

24 are metal blocks soldered or otherwise secured to the cuspidor body 10, and to which the bars 21 and 22, respectively, are fastened in order to additionally support and stiffen the structure.

The operation of my invention has been so fully described in connection with the description already given that further explanation is deemed unnecessary, and while I have shown the preferred embodiment of my device it is obvious that minor changes may be made, such for example as attaching the bifurcated ends of bars 21 and 22 directly to the cuspidor body 10 instead of to the ring 17, and I therefore do not desire to be limited to the exact construction shown, but

What I do claim as new and wish to secure by Letters Patent of the United States is- 1. The combination, with a vertically movable cuspidor, of a two-part hinged cover, vertically reciprocating arms connected rigidly to the cuspidor and with said cover members by pivots remote from their hinges, a spring for normally raising the arms and foot operated means for lowering them.

2. The combination, with a vertically movable cuspidor, of a pair of quadri-spherical cover members hinged to each other and to the cuspidor support said cover members having pivot pins remote from their hinges, arms fastened to and moving with the cuspidor and also connected with said pivot pins, a spring for normally raising the arms and foot operated means for lowering them.

3. The combination, with a vertically movable cuspidor, of a pair of quadri-spherical cover members hinged to each other and to the cuspidor support said cover members having pivot pins adjacent to their hinges, arms secured to and moving with the cuspidor and having slots to receive the pivot pins said slots extending transversely of the direction of movement of the arms, a spring normally raising the arms and foot operated means for lowering them.
